# SOAP Monitor Tracer

The Tracer shows the SOAP messages, the respective SOAP message requests and responses - when the services are deployed on the server, and the invoked operations. By default, this feature is turned off. You have to turn it on to enable tracing.

Warning: Turning on the Tracer feature will have a drag on the performance. This is because all the SOAP messages will always be completely built (i.e., deferred building will not be done) and stored in the database by WSO2 Data Services. Hence this option should be used with caution.

Figure 1: Turned OFF SOAP Tracer

1. In the navigator, under Monitor, click SOAP Message Tracer. The SOAP Message Tracer page appears.
2. In the Status field, click On. The tracer will show the messages of the operations that were invoked.

By using the SOAP tracer, you can see the SOAP messages with their time-stamps, service name, operation invoked and the number of requests to the server. The most recent SOAP messages are listed on the top. When a particular SOAP message is selected, its request and the response can be viewed.

Note: This tracer does not apply to operations invoked in the admin services, as they are filtered out.
